Password is a simple technique users do use to protect and authenticate their private information. It is employed popularly as an effective way in most computer applications and services in the early information security. Afterwards, due to the weakness of length and some bad habits of users make password be vulnerable to attacks, the key stretching and especially, password hashing techniques were presented to fix the problems and provide a stronger protecting. Both have hash functions within as major elements. However, hash functions just focus on hashing and storing password, not security at all, that leads to the need of more effective and secure techniques. Several advanced password hashing schemes were proposed, such as PBKDF2, bcrypt, and scrypt. Recently, Password Hashing Competition (PHC) was occurred to give more supplementary choices, besides the three mentioned schemes above, that are suitable for widespread adoption of modern information era. Along with other effective algorithms, the final PHC winner, Argon2, is a remarkable secure design which shows high performance and high resistance against most known attacks. In this paper, we give a general overview about password hashing techniques from beginning to present, measures and evaluates security aspects of recent password hashing schemes (through Password Hashing Competition), and also makes a prediction of future password hashing in information era so far.
